ROBERT HABERTHR AND RUDOLPH BRENNER, OF NEW YORK, N. Y.

RETORT-DOOR.

SPECIFICATION forming part of Letters Patent No. 392.202. dated November 6, 1889.

Application filed October 7, 1887. Serial No. 251,730. (No model.)

To @ZZ whom t may concern:

Be it known that we, ROBERT HAEEETHR and RUDOLPH BRENNER, both of New York, county and State of New York, have invented a new and Improved Door for Retorts,of which the following is a specification.

This invention relates to a door for gas-retorts, so constructed that it may be adjusted to make tight joints with the door-frame.

The invention consists in the various features of improvement, more fully pointed out in the claims.

In the accompanying drawings, Figure l is a face view of our improved door for gas-retorts; Fig. 2, a sectional top View thereof; and Flg. 3, a vertical central section on theline x w, Fig. l.

The letter arepresents the door-frame, made of D form and adapted to be secured to the mouth of a retort.

b is the door, hinged upon a pintle, c, the ends of which are secured to lugs (Z, projecting rearwardly from vframe a. The door is hung upon the pintle by means of an arm or block, f, having the two cylindrical sleeves ff", that embrace pintle e. The bore of each sleeve is somewhat larger in diameter than the diameter of the pintle, Fig. 2, so that the door has a play uponits pivot.

ofthe sleeves f and abutting against pintle c, the screws g g being placed opposite one another and the screws h h being also placed opposite one another. By loosening the screws gand tightening up the screws g', or vice versa, the door may be shifted laterally, and by operating the screws h h in similar manner the door may be thrown farther inward or outward. Thus the door may be adjusted in four different directions.

The inner edge of the frame a should be beveled, Fig. 3, and the door should be correspondingly beveled to make a goed joint. The lowermost bar, a', of the frame a is cut away at the front to accommodate a slide, o', bearing against the lowermost edge of door b. This slide has also a beveled top edge, and it is held to the bar a by means of a pair of screws, j, passing through elongated upright slots in slide By first loosening these screws the slide may be moved upward'toward the door, when the joint is to be tightened up, after which the slide may be locked in place by the screws.

7c is a 1ocking-bar pivoted to doorb by pivot Za and free to be oscillated between stops k2. The free end of the bar 7s may be engaged and pressed against the frame a by means of a camlever, Z, pivoted to a lug, m, on such frame. The cam-lever is placed in front of the locking-bar, as shown, so that the locking-bar is interposed between the door and cam. The cam-lever Z is provided with socket or sleeve Z for the introduction of a hand-lever. The door is unlocked by swinging the cam-lever aside, and then Swinging the locking-bar upward to clear such lever, after which the door may be opened.

What we claim is l. The combination of door-frame e, having lugs d, with pintle c, secured to such lugs, and with door b, having sleeves f', that embrace the pintle between vlugs d, and which have a bore greater than the diameter of the pintle, and with the screws g g', 7L h', passing through sleeves f and abutting against pintle c, subg g and h h. are screws passing through each stantially as specified.

2. The combination ol` D-shaped frame a, beveled at its inner edge, with a hinged beveled door, b, and with a slide, t', secured to the bar e' of frame a and bearing against the edge of door Z1, substantially as specified.

3. The combination of door b, having pivn oted locking-bar Zz, with door-frame a, having lug m, and cam-lever Z, pivoted to lug'm, and provided with socket Z, the locking-bar k being placed between the door and the eanrlever, substantially as speciiied. u
